ELECTRIC-LAMP HANGER.

SPECIFICATION forming part of Letters Patent o. 397,953, dated February19, 1889.

Application filed August 23, 1888. Serial Nn. 283,585. (No model.) l

To all whom it may concern.-

Be it known that'I, MONTRAVILLE M. Woon, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Electric-Lamp Hangers;and I do hereby declare the following to be .a full, clear, and exactdescription of the invention, such as will enable others skilled in the1o art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon, forming part of this specification. l

My invention consists in the improvements in electric-lamp hangershereinafter set forth and described, and illustrated in the accompanyingdrawings, in which- Figure I shows a side elevation, with parts 2othereof in section, of my improved hanger with an electric lampsuspended thereon. Fig. 2 shows a like view of same with the lampunliooked to be lowered down. Fig. 3 shows a view of a modifiedconstruction of my device.

Like letters refer to like parts in all the figures.

In the construction of my invention shown,4 A is a cable adapted tosupport an electric 5o lamp over the center of 'a street or at any otherdesired point. On this cable A, I place a grooved block, B,adapted toslide on said cable, and to the sides of the block B, I secure astirrup,B, ol' sufficient strength to support the weight ot' a lamp. Inthe lower end of the stirrup B', I provide an insulating-roller, d,which is mounted upon the cross-bolt c, connecting the lower ends of thesides c of the stirrup B together.

4o In the groove c, in which the cable A operates, I place a hook, O,mounted on a pintle, l), which passes through the block B from side toside. The shank f of the hook C, through which the pintle b passes, isin the form of an eccentric, which the strain of the rope E on the hookC operates to rotate on the pintle l), so as to clamp the cable A iirmlyin the block B. In the hook C, I secure a small pulleyblock, D, throughwhich a small suspending- 5o rope, E, passes to the S-shaped hook F, the

upper end, 7L, of said hook F being secured to the end of the rope E,and the lower end, K, thereof engaging with the ring g in the top of thelamp G. In the center of the hook F,

I pivot a tongue, H, adapted to be thrown up by contact with the lowerend of the stirrup B', so that the upper end of the ,hook F will pass bythe roller d and allow the lamp G to be lowered 4down when desired, theopposite end of the rope E, passing over a pulley on 6o the pole, (notshown,) supporting one end of the cable A.

In Fig. 3 I show a modified form of my invention. Instead of thecam-hook C in the block B, I use an ordinary hook, C', in the 65 groovea for supporting the pulley D, and in lieu of clamping the block B tothe cable A, to prevent the longitudinal movement of the block Bthereon, I secure a rope, I, to the block B by means of a stirrup, J, orin any 7o other convenient manner, which rope is secured to the cable-supporting pole (not shown) at the side of the street opposite `to thatat which the end of the rope E is secured, so as to withstand the strainof the rope E on the block B. v

Having thus fully described my invention, so as to enable others toconstruct and use the samevhat I claim as new, and desire to secure v bvIiet-ters Patent of the United States, is- 8o l. The combination, in anelectrical-lamp hanger, of a block adapted to slide and rest upon asupporting-cable with a hook having a Cain-shaped shank pivoted in saidblock and adapted to be turned on its pintle so as to clamp thesupporting-cable against said block,

a pulley suspended from said hook, and a rope operating in said pulleyfor raising and lowering a lamp suspended therefrom, substantially asand for the purpose set forth. 9o

2. The combination, in an electric -lamp hanger, of a block adapted toslide and rest upon a supporting-cable, a hook pivoted in said block,and a pulley suspended thereon with a stirrup secured to said block andprojecting downward therefrom7 a rope passing through said pulley anddownward through said stirrup, and an S-hook on t-he lower end of saidrope adapted to support a lamp, and a tongue pivoted to said S-hook soas to close the up- 4Ico per lmll of said S-hook and prm'entitsengagement with said stirrup when the lamp is being lowered,substantially as and lfor the purpose set forth.

3. The combination, in au eleetrielamp hanger, of u groovedsupporting-block, B, huying u hook, l, pivoted therein, with a rigidstirrup, B', secured to said block B and hwing` an insulator, d, in thelower end thereof, u lamp raising` and lowering rope, E, passing througha pulley suspended from said hook C and through the stirrup B', miS-liook, F, seeured to said rope and adapted to suspend :L lmnp to thestirrup B', and a tongue, H, on said S-hook. F, adapted toelose upagainst the upper half of the hook F when it is lowered past the lowerpart of the stirrup B', suhstantially ns fm d 'furthe purpose sei:forth.
